Embodiment
In order that those skilled in the art more fully understand the technical scheme in the present invention, below in conjunction with of the invention real
The accompanying drawing in example is applied, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described implementation
Example only part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, should all belong to protection of the present invention
Scope.
Fig. 1 is refer to, Fig. 1 illustrates the cable anti-theft device structural representation that a preferred embodiment of the present invention is provided.Such as
Shown in Fig. 1, the cable anti-theft device 100 includes theft management module 110 and theft-proof terminal module 120, wherein, theft management
Module 110 and theft-proof terminal module 120 are arranged on cable L both ends.
Wherein, theft management module 110 includes the first power carrier communication unit 111 and the first radio communication unit 112；
Theft-proof terminal module 120 includes the second power carrier communication unit 121 and the second radio communication unit 122.
First power carrier communication unit 111 is communicated with the second power carrier communication unit 121 based on cable L, is prevented
Management module 110 is stolen according to the communication shape between the first power carrier communication unit 111 and the second power carrier communication unit 121
Condition tentatively judges whether cable L occurs exception.Specifically, in the present embodiment, the first power carrier communication unit 111 with
Second power carrier communication unit 121 is based on directly on what cable L was communicated, that is to say, that during communication disruption, shows current
Cable L occurs being likely to occur abnormal conditions, such as disconnects, or shows to be currently peak times of power consumption, and communication receives interference.
When theft management module 110 finds the first power carrier communication unit 111 and the second power carrier communication unit 121
Between communicating interrupt when, then it is preliminary to judge that cable L be compromised, but in order to avoid erroneous judgement, as described above, communicating
Interrupt be also possible to be due to electrical equipment on current cable L it is excessive caused by interference, theft management module 110 may proceed to
By the communication condition between the first radio communication unit 112 and the second radio communication unit 122, to determine whether cable L
Whether breakage is occurred.
Specifically, be between the first radio communication unit 112 and the second radio communication unit 122 by wireless signal come
It is in communication with each other, therefore the transmission of signal is not influenceed by electrical equipment on cable, and the work of the second radio communication unit 122 is electric
Stream comes from cable, so when not having electric current transmission on cable, the second radio communication unit 122 can not normal work, then
Exception, theft management module will occur for the communication between the first radio communication unit 112 and the second radio communication unit 122
110 can determine that cable currently disconnects, then it is regarded as cable and infringement occurs, so as to be further processed, such as
Given a warning to background service system, abnormal information is recorded etc..
In summary, the theft management module 110 in the antitheft cable device 100 that the present embodiment provides carries in the first electric power
During 111 and second power carrier communication 121 communication abnormality of unit of ripple communication unit, by the first radio communication unit 112 to
Two radio communication units 122 send confirmation signal, and judge whether cable L goes out according to the feedback of the second radio communication unit 122
It is now abnormal.The cable between theft management module 110 and theft-proof terminal module 120 can not only be monitored in real time, and be led to
The mode that increase wireless telecommunications confirm is crossed, is further ensured that the accuracy of monitored results.
Theft management module 110 and theft-proof terminal module 120 will be illustrated respectively below.
Fig. 2 is refer to, Fig. 2 illustrates the electrical block diagram of theft management module 110 in embodiment illustrated in fig. 1.

As can be seen here, the cable anti-theft device that embodiments of the invention are provided, set by the both ends of cable loop
Theft management module and theft-proof terminal module, both are based on cable and carry out PLC communications, can tentatively judge whether cable is normal,
When there is communication abnormality, then wireless telecommunications are initiated, determine whether cable exception occurs, it is achieved thereby that the antitheft prison to cable
Control, and the accuracy of monitored results is largely ensure that, avoid judging by accident.
In an embodiment of the present invention, PLC communication is realized based on cable, when there is power supply on cable, PLC
Power supply of the operating current of communication from cable, and when on cable because of normal set without powering, such as road
Lamp cable during the day do not powered by section, and PLC communications are then powered by battery, to ensure normal work, at this
In the case of, communication is realized because PLC communications are based entirely on from carried charge, and it is served only for signal independent of cable power supply, cable
Transmission, therefore under this environment, if PLC communications occur it is abnormal, then can directly determine that cable breaks down.PCL
Communication can be lasting or Fixed Time Interval.
Wireless telecommunications only start when PLC communications occur abnormal, the power supply of its cable that places one's entire reliance upon, therefore it only has
There is ability normal work in the case of powering on cable, as described above, can be straight when there is no normal power supply on cable
Connect the situation based on PLC communications and determine whether cable exception occurs.

Block 410 tentatively judges cable according to the communication condition between the first power carrier communication unit and the second power carrier communication unit
Whether exception is occurred.Specifically, in the present embodiment, the first power carrier communication unit and the second power carrier communication list
Member is based on directly on what cable was communicated, that is to say, that during communication disruption, shows that current cable occurs being likely to occur exception
Situation, such as disconnect, or showing to be currently peak times of power consumption, communication receives interference.
When theft management module 410 is found between the first power carrier communication unit and the second power carrier communication unit
It is during communicating interrupt, then preliminary to judge that cable be compromised, but in order to avoid erroneous judgement, as described above, the interruption of communication
Interference caused by the electrical equipment that is likely due on current cable is excessive, theft management module 410 may proceed to by the
Communication condition between one radio communication unit and the second radio communication unit, to determine whether cable breakage occurs.
Wherein, the anti-theft communication mode between theft management module 410 and theft-proof terminal module 420 and circuit structure are specific
Reference can be made to shown in Fig. 2 and Fig. 3 and word description part, will not be repeated here.
In the present embodiment, the pattern of multiple theft-proof terminal modules is correspondingly managed by a theft management module can realize pair
Cable in the range of some carries out Centralized Monitoring and processing, save device resource and maintenance cost, and more can closing to reality
Use demand.
In addition, being based on above-mentioned cable anti-theft device, the present invention also provides a kind of cable theft-prevention method.
Fig. 5 is refer to, Fig. 5 illustrates the cable theft-prevention method flow diagram that a preferred embodiment of the present invention is provided.Such as Fig. 5 institutes
